Only the educated are free.
Go for it now. The future is promised to no one.
The wise does at once what the fool does at last.
Do not weep do not wax indignant. Understand.
Without hard work, nothing grows but weeds.
Wherever you are - be all there.
The most effective way to do it, is to do it.
You never know what motivates you.
If you think you can do it, you can.
If you're going through hell, keep going.
I have taught history on the high school and college levels, and am or have been a lecturer at the Smithsonian, The National Institutes of Health, and numerous colleges and universities, mostly on science fiction and technology subjects.
